Abstract AR
تم عزل و تشخيص 22 نوعا من الفطريات التي تعود ل 13 جنسا من تربة أهوار محافظة ذي قار، و تراوح معدل أعداد المستعمرات الفطرية بين 1550 – 4150 مستعمرة / غم تربة.
و حققت الأجناس Aspergillus و Alternaria و Cladosporium و Stachybotrys و Phoma نسب ظهور عالية في عينات التربة و بلغت 98.67 % و 82.67 % و 69.33 % و 57.0 % 52.0 % على التوالي.
أما الأنواع الفطرية التي ظهرت بنسب عالية في عينات التربة فهي : A.
flavus و A.
terreus و C.
cladosporioides و Paecilomyces variotii و Ulocladium botrytis سجلت أدنى نسب للظهور و بلغت 8 % و 12 % و 13.33 % و 6 % على التوالي.
أعطت 9 أنواع من الفطريات المختبرة كشفا موجبا لأنزيمات Cellulase و Amylase و Lipase و Protease و هي : Alternaria chlamydospora و Aspergillus flavus و A.
fumigatus و A.
terreus و spicifera Bipolaris و Fusarium oxysporum و Exserohilum rostratum و Trichoderma viride و Ulocladium botrytis.
و تميزت الفطريات Cladosporium cladosporioides و A.
candidus و flavus A.
و B.
spicifera بإنتاج مميز لأنزيم Cellulase، أما الأنواع flavus .A و Stachybotrys atra و T.
viride فقد كانت متميزة بإنتاج أنزيم Amylase.
كما حققت الأنواع A.
flavus و F.
oxysporum و atrum U.
أعلى فعالية في إنتاج أنزيم Lipase، و أظهرت الأنواع A.
candidus و A.
flavus و T.
viride فعالية في إنتاج أنزيم Protease.
Abstract EN
A survey on soil mycoflora in Thi-Qar marshes have been studied.
A total of 22 fungal species belonging to 13 genera were isolated and identified.
The average of the total fungal colony count ranged between 1550-4150 colonies/gm of soil.
Aspergillus, Alternaria, Cladosporium, Stachybotrys and Phoma were of the mostly occurred genera in soil samples constituting 98.67%, 82.67%, 69.33%, 57.0 % and 52.0 %, respectively, and the mostly occurred species were; A.
terreus, A.
flavus, C.
cladosporioides and S.
atra; constituting 74.67 %, 69.33 %, 69.33 % and 57 %, respectively.
Nine fungal species : Alternaria chlamydospora, Aspergillus flavus, A.
fumigatus, A.
terreus, Bipolaris spicifera, Fusarium oxysporum, Exserohilum rostratum, Trichoderma viride and Ulocladium botrytis were identified to produce the four investigated enzymes : cellulase, amylase, lipase and protease.
All the tested isolates were identified as cellulase and amylase producers, A.
candidus, A.
flavus, B.
spicifera and C.
cladosporioides were an excellent producer of cellulase, while A.
terreus, Stachybotrys atra and T.
viride were the most active amylase producers.
A.
flavus, F.
oxysporum and U.
atrum showed the highest lipase production.
The higher activity of protease was produced by A.
candidus, A.
flavus and T.
viride.
